Abstract

The invention relates to a radiotherapy device and method of gamma ray rotation and focusing, which comprises the following steps: main control unit, driver, radiation device, therapeutic bed and so on, wherein the therapeutic bed and rotatable barrier are set in the rotating ring and radiation device separately; the rotating support ring is fixed on two ends of rotating stand with the axial of rotating support ring matching rotating ring positionally; the relating radiation device is set between two rotating rings, whose the rotatable barrier center fixes a rotatable cylindrical alignment. The character of the invention in comparison with the present technique comprises the following: the cylindrical alignment and source bulk rotate in the radiotherapy device simultaneously; the single-layer and double-support structure augments the range of rotating ring in comparison with the present double-rotating rings and double-support structure. The device expands the mobile range of the therapeutic bed in the rotating ring, which expands the treatment space and reduces the making cost and difficulty.

Description

technical field [0001] The present invention relates to radiation medical equipment, in particular to a radiation therapy device for gamma ray rotational focusing and its operation and use method in the treatment process. Background technique [0002] In the radiation therapy using the radiation therapy device, the working principle of rotating focus is used to rotate and irradiate the patient's lesion, so that the lesion tissue at the rotating focus point is irradiated with the maximum dose, and the healthy tissue is irradiated with an instantaneous and tolerated dose. Thereby killing the lesion, protecting the healthy tissue around the lesion, and achieving the purpose of radiation therapy. Chinese Patent Publication No. CN 1275410 discloses a radiotherapy device for multi-source radiation systemic therapy, which includes: a source body, a source body rotary ring fixed with the source body, a collimator, and a collimator fixed with the collimator. The collimator slewing r...
